Command-line encoder/decoder

The base Speex distribution includes a command-line encoder (speexenc) and decoder (speexdec).

speexenc

The encoder takes the following options:

-narrowband (-n)

Tells Speex to treat the input as narrowband (8 kHz). This is the default

-wideband (-w)

Tells Speex to treat the input as wideband (16 kHz)

-quality n

Set the encoding quality (0-10)

-vbr

Enable VBR (Variable Bit-Rate), disabled by default

-nframes n

Pack n frames in each Ogg packet (this saves space at low bit-rates)

-comp n

Set encoding speed/quality tradeoff. The higher the value of n, the slower the encoding (default is 3)

-V

Verbose operation, print bit-rate currently in use

-help (-h)

Print the help

-version (-v)

speexdec

The decoder takes the following options:

-enh

enable post-filter

-no-enh

disable post-filter (default)

-V

Verbose operation, print bit-rate currently in use

-help (-h)

Print the help

-version (-v)
